Review on Strengthen your Forearms with the NSD Power Lit Spinner Gyroscopic Exerciser - Boosted by LED Light Innovation by Robert Correa

I've only had this product for a few days, but it has worked as described! I am a climbing addict and always looking for low injury grip, hand, wrist, ligament and forearm workouts. This product is incredibly easy to use (if you can't use a brake cable then you probably can't read either, so ignore this review) and works extremely well. If you love bouldering like me or do any type of arm endurance sport, I recommend this product.
